How can the company meet this requirement?
Place the EC2 instances in two separate AWS Regions connected with a VPC peering connection.
Place the EC2 instances in two separate Availability Zones within the same AWS Region.
Place one EC2 instance on premises and the other in an AWS Region. Then connect them by using an AWS VPN connection.
Place both EC2 instances in a placement group for dedicated bandwidth.
Explanations:
Placing instances in separate AWS Regions would ensure they are in separate data centers, but it increases latency, which does not meet the low-latency requirement.
Separate Availability Zones within the same AWS Region provide redundancy across data centers with minimal latency due to close proximity and AWS network optimization.
Using on-premises and AWS Region instances increases latency due to the VPN connection over the internet, which is unsuitable for low-latency needs.
Placement groups offer low-latency network performance within the same AZ, not across separate data centers. This option does not provide data center separation.
In my opinion, the answer is:
Place the EC2 instances in two separate Availability Zones within the same AWS Region.
I map out that the answer is:
Place the EC2 instances in two separate Availability Zones within the same AWS Region.
